Tellabs Unveils Industry-Leading Digital Cross-Connect for Customers' Evolving Networks



Smaller, more powerful design delivers enhanced capacity in a reduced footprint

NAPERVILLE, Ill., Sept. 18 -- Proving good things do come in small packages, service providers can now get even more capacity while saving valuable space in central offices and mobile switching offices. This benefit comes from Tellabs' reinvention of its industry-leading digital cross-connect. The new Tellabs(R) 5500 digital cross-connect system delivers all the capabilities of the Tellabs(R) 5500 system, plus enhanced administration, greater engineering flexibility and cost-structure improvements.

"Service providers face a capacity conundrum -- the successful introduction of new integrated applications and continued T-1 growth creates the need for more bandwidth in already constricted switching offices," said Dan Kelly, executive vice president, transport products for Tellabs. "In response, Tellabs is evolving the Tellabs 5500 system. These new capabilities build on technology that has set the standard for wireless and wireline transport networks, and create a new system to meet service providers' evolving needs."

The new Tellabs 5500 system offers:
-- A consolidated core switch design that increases switch capacity by 50% while reducing floor space requirements by 78% (for picture: tellabs.com/news/2006/tellabs5500new.gif ).
-- Cost-effective migration of wireless backhaul network from 2G to 3G, as part of the Tellabs(R) IntegratedMobile(SM) solution.
-- Lower operating expenses through a new high-speed OC-48 interface, reducing the need to purchase additional add/drop multiplexers (ADMs). The Tellabs 5500 system also connects directly to routers and Asynchronous Transfer Mode (ATM) switches.
-- Enhanced Ethernet transport capabilities, including standards-based Ethernet over Synchronous Optical Network (SONET). This benefit enables cost-effective Ethernet service delivery and aggregation over existing infrastructure.

The Tellabs 5500 system carries voice and data traffic over communications networks and is the leading digital cross-connect system in the United States, according to industry analysts. A majority of North America's wireless calls are made on mobile networks owned by Tellabs' customers.
